DISK-CUTTING MACHINE. s

Application lediAugust 10, 1917. Serial No. 185,492.

To all fur/mm, t may concern.'

Be it known that I, ALEXANDER BOG- DNFFY, a former subject of the King of Hungary, and who have declared my intention of becoming a citizen of the United States, and a resident of Brooklyn, in the county of 4Kings and State of New York, have invented certain new and useful Improvenients in Disk-Cutting Machines, of which the following is a specification.

`The invent-ion relates to machinery employed in connection with the manufacture of closures, for example of the character of the so-called crown corks, and pertains more especially to a machine for cutting out the disks of cork or similar' material with which said crown corks are lined.

The invention has for its object to pr vide a machine designed to receive the cork in the form of strips or sheets, and to cut therefrom ina simple and expeditious manner, and with a minimum of operations, disks of the desired diameter. A further object of the invention resides in the manner of presenting the material to the cutters for the cutting out of the disks, and whereby the use of special ejecting means may be dispensed with, the arrangement, furthermore, being such that the cutters may be readily sharpened and adjusted.` A still further object of the invention consists in a positive feeding means for advancing the cork strip with reference tothe cutters.

In the accompanying drawings, which illustrate the invention- Y Figure 1 is a `front elevation of the machine, aportion thereof being shown in vertical section. l

Fig. 2 is a plan thereof, a portion of the mechanism being removed to disclose the supporting platform and cutters.

Fig. 3 is a side view.

Fig. 4: isan end View with a portion of the apparatus omitted. t Y

Fig. 5 is a detail View illustrating the feeding and cutting mechanism. i

Similar characters of reference designatev corresponding parts throughout the several views. l

Referring to the drawings, 10 designates asuitable supporting structure having a platform 11 at one end, and in which are rotatably mounted a plurality of tubular cutters 12 for effecting the cutting out of circular cork disks of the desired diameter ing or similar machine (not shown).

from strips of natural cork or other suitable material as the same is received from a slic- These cutters are axially immovable with refer, ence to said platform and structure, and are spaced preferably two in front and one in back and between the two said forward cutters, whereby three disks will be simultaneously cut-out by each unit. In the mechanism herein illustrated, two units are shown, being exactaduplicates; but it is to be understood that the invention is not restricted to any particular number of said units, and the operation of but one such unit will be considered herein. These cutters may be of any well-known or special design, and are rotated from a suitable sourceof power (not shown) through pulleyslll and 14 and belt 15, spools 16 being provided on said cutters to receive the said belt. No claim is made to the manner of'driving these cutters as well as their particular construction; but it is believed novel to mount them in iXed relation to the supporting structure.

To the supporting structure 10, at its opposite end, is pivotally secured, as on the shaft 20, a supporting frame or arm, or rather a pair of arms, 21, which carries the entire material-retaining and feeding mechanism. These mechanisms are so arranged that when the frame 21 is swung into the norma] position, shown; in Fig. 3 of the drawings, the various mechanisms will be in proper relationship to the cutters for ef? fecting the cutting out of the cork Idisks from the material retained thereby. These disks, when thus cut from the material, will drop through the tubes by the action of ravity; or, in case the location of the tube 1s such that the disks will stack therein, the said disks will be `gradually forced outwardly as they accumulate. Furthermore, should it be desired to sharpen these tubular cutters, the same` are rendered readily accessible for thisV purpose by merely raising the frame 21, the entire mechanism moving about the shaft 2 0 and being lifted olf the platform 11 which retains the said cutters.

The mechanism for retaining the. cork material 25, Fig. 5, in position to present it to the cutters consists essentially of a meli ber composed of a lower plate or table 26 having circular perforations 27 therein registering with the edges of the cutters, but normally slightly beyond same, and of the desired diameter of disks to 'be cut'. The

plate 26 is movably mounted on rods 28 and has lateral upturned portiens 29 which serye to guide the cork material as nell( as ya fuither plate or member 30, also mounted upon said rods but ixedly secured thereto, the spacing between said `twoplates lic-:ingadjusted forthe normal thickness of the material fi'oiii which the"disks are to be eut. This plate 30 may be secured in any Vconvenient 'manner 'to the vrods' 28, andthe spacing between the twoplates' is insured by nieans of suitable washers 31 intei'posedbei tween 'the rod-engaging portions of 'the Esaid tivo plates. 'Furtlier'inoi'eg in order to a'ccommodate for irregula'ritiesin the' thickness of the material," the lower plate 26 is yieldiiigly held to the plateI 30 as means of springs 32 coiledlabout the 'lower ends of `said ti'ods, one" end of`.,a. spring bearing a,`9;aiiist*said plate, and tlief'other against a suitable stopor pin 33 of saidrods It will be noted, thus, 'that-the upper plate '3Qv is in fixed relationship to the cutteis'aiid Vrods and movablejonly as a unit with the latter relatively to the =former',1 iyhereas the `lonrer plate't may yield ielatiifely to said ycutters independently' of tly'ieliii'citenieiitof the rods. The upper plate", furthermore, is provided inith alongitiidinal'slot 35 along'its median .line and carries cani-engaging surface 36. The i'o'ds`28r, tliemselifes are i'noyableas a Whole `with the tnfoplatesaiid members carriedwthereby `when theeam surface of `the upper plate is engaged by a suitable cam, as hereinafter set forth, to depress the said retaining ineii'ib'er toiy'ar'd the lcutters to effect the Vcutting utfofthe disks'` fron'i the material retained between the said plates. To lr'estorethe retaininginembiei' to normal positioii,fslio\vriin Fig. l of the c`li'awings, when the. cam pressurewis released, springs, 3,7 ,dle coiled 'abouttliie 4upper portions of said rods arid'beai' against pins 38 at one yen dtheigeofffandiianged lower extensions4 21 of the y fraineQl at the other.'

For athe Vpurpos'e, of effecting cutting out action, a canitO is rotatably niountedfin the frame 21, and is located preferably inidfifvay bet'nieeii'lthe tufo rods 28, and in such "folrfeizaiiiple, of a lyon withh 'todtheld1 iunder i ""Of bli' *iiiaiteriaias to aifoid,liiorinally, a sufiicient it* iti A v v u tu ally restores the .grippe oted frame Q1 carrying the'mechanism hereinbefore described is of sufficient Weight, or mayI be` locked to tliewsupporting structure 10, to resist the upward reaction of the cam shaft when the cam 40 engages the cam-engaging surface 3G to depress the Work towardand against the cutters.
